You Don’t Need an Internal Device: How External Light Therapy Relieves Menopause Dryness & Leaks
If you're dealing with vaginal dryness, burning, or sudden bladder leaks after menopause, you're experiencing what doctors call GSM (Genitourinary Syndrome of Menopause). And if the thought of inserting anything into your vagina to treat dryness, leakage, or discomfort makes you want to close this tab I want you to know something first: that's a completely valid reaction, there are many women who prefer not to use an internal ‘wand’ device. Over the past few months I’ve been hearing from more women who prefer a non-invasive approach - they have very personal reasons for not wanting to use a device that goes inside the vagina and we now have science to back it up as a valid option.
(When most women hear 'light therapy wand,' they think of a red-light face tool for wrinkles. But in the pelvic health world, 'wands' or internal probes refer to devices designed for vaginal insertion to treat tissue changes from menopause).
Plenty of women don’t want a ‘wand’, not because they're squeamish, but because insertion itself can be genuinely difficult or even a non-runner. If you're dealing with vulvodynia, vaginismus, or a history of pelvic trauma, or you're simply not there yet, you deserve options that meet you where you are, not just where the marketing assumes you should be.
So let's talk about what's actually possible with an external-only approach, what the research says it can help with, and - just as importantly, what it can't do yet, so you can make a decision based on real evidence instead of guesswork.
Is external or internal red light therapy the best option for you?
First, What "External" Actually Means
We’re talking about a small handheld cold laser device held just against or just above the skin, never inserted, just applied to the outside of the vulvar tissue for a short period. No probe. No insertion. You stay fully clothed from the waist up, and the only thing that happens below the waist is light passing through skin, the same way it would on any other part of your body during a light therapy session.
This is the exact approach used in a recent, published clinical trial out of Brazil, a placebo-controlled, double-blind study, which is the gold standard for this kind of research. Sixty-five postmenopausal women with genitourinary syndrome of menopause (the umbrella term for the dryness, burning, and urinary symptoms that show up after estrogen drops) were treated with an 808-nanometer laser, applied externally to the vulvar region.
What the Study Actually Found
In this 2026 RCT - 65 postmenopausal women, all over age 50, all reporting at least one GSM symptom (dryness, burning, or urinary leakage). They were split into two groups by random assignment (like a coin flip, not by choice), one group got the real laser treatment, the other got the exact same routine with the device switched off. Neither the women nor the person delivering the treatment knew which group was which until the study was over. This is called "double-blind," and it's the strongest possible design for ruling out the placebo effect, meaning any improvement in the real-treatment group can't just be explained by women expecting to feel better because they were being treated.
The external-only approach showed a real, statistically significant improvement in two specific areas: urinary incontinence and vaginal dryness and burning. If those are your main complaints - the leaking, the rawness, the constant awareness of discomfort down there, this is genuinely encouraging, peer-reviewed evidence that a non-invasive option can help.
What it did not show a significant improvement in was sexual function or pelvic pressure, measured using a well-known sexual health questionnaire. And when I first read that result, I thought it didn’t make sense. If dryness and burning genuinely improved, shouldn't sex feel at least somewhat better too? They seem so obviously connected. So I want to walk you through why these two things can move in different directions, because I think understanding the "why" makes this research more trustworthy, not less.
Why Dryness Can Improve While Sexual Function Doesn't - Solving the Puzzle
Here's the first piece: the sexual function questionnaire researchers use isn't one simple question like "is sex better?" It's actually 19 separate questions, grouped into six categories, desire, arousal, lubrication, orgasm, satisfaction, and pain which all get averaged together into one final score. Physical dryness mainly affects just one or two of those six categories, lubrication and maybe pain. It has almost nothing to do with desire, orgasm, or overall satisfaction, which are shaped by completely different things, like mood, stress, body image, and what's happening in a relationship. So imagine six students getting graded on a group project, and only two of them actually improved their part, the group's average grade might barely move, even though real, specific progress happened. That's essentially what can happen to a composite sexual function score.
The second piece is even more human. Painful sex after menopause often becomes what researchers call a cycle: dryness causes pain, pain creates anxiety and dread around sex, and that anxiety itself lowers arousal and natural response, sometimes long after the original physical problem has actually improved. The study was run over four weeks which is a very short window for a tissue-level fix to also unwind months or years of built-up hesitation, avoidance, or a couple's unspoken adjustment around avoiding intimacy altogether. It's a bit like physical therapy for a sprained ankle - the swelling can go down and the joint can genuinely move better, but the flinching and careful, guarded way someone walks doesn't disappear the moment the swelling does. The tissue and the behavior built up around protecting it often heal on two different timelines. (My menopause protocols are usually 12 weeks for optimal results).
So my honest read is this: the fact that dryness and burning improved while the overall sexual function score didn't isn't a contradiction, and it isn't a sign the treatment "doesn't really work." It's a reminder that sexual wellbeing is genuinely more complicated than tissue health alone, and that a four-week study measuring six different things at once is always going to tell a more layered story than a single yes-or-no headline can capture. I'd rather explain that nuance to you honestly than round the results up or down to make a cleaner-sounding claim. (Interestingly a US study using transcranial red light therapy (red light applied to two points on the forehead) significantly improved sexual function in a randomized control trial). More to come on this and other uses of the Solasta laser for menopausal health.
How Could Light ‘Down There’ Help My Bladder?
This is the question almost everyone asks, and it's an important one.
Near-infrared light in this wavelength range can only travel a short distance through skin and soft tissue, a few millimeters to about a centimeter under realistic conditions, not several inches. So it's fair to ask: how does that reach anything that matters?
Here's the piece that makes it click: the structures actually responsible for urinary leakage and vulvar dryness sit much closer to the surface than most people realize. Stress urinary incontinence happens largely because of two related problems: urethral hypermobility, where weakened pelvic floor muscles and vaginal connective tissue no longer hold the bladder neck and urethra firmly in place, and reduced collagen density in that same supporting tissue, especially after childbirth or estrogen decline. The urethra and its surrounding supportive tissue, the part that weakens and loses tone after menopause, which is a major reason for leaking, sit right at that shallow depth the light can reach. It's not traveling all the way to your bladder, and it doesn't need to. It's reaching the tissue immediately beneath where the device is held, the tissue actually responsible for the symptom being treated. Think of it less like a flashlight trying to shine through a wall into the next room, and more like sunlight warming the top layer of soil enough to help the roots just beneath the surface.
At the cellular level, this light is absorbed by structures inside your cells' mitochondria, the same "energy factories" in every cell in your body, boosting their ability to produce energy and triggering a cascade of repair signals, including the release of nitric oxide, which improves local blood flow. It's a slow, cumulative, cellular-repair process, not an instant fix, which is part of why these studies run for several weeks rather than showing change overnight.
So Who Is This Actually a Good Fit For?
I want to give you a clear way to think about this, based on what your main complaint actually is, because "does light therapy work for menopause" is too broad a question to answer honestly. The real question is which symptom you're trying to solve.
If your main struggles are leaking, dryness, or that raw, burning feeling, the external-only approach has direct, published trial support. This is a legitimate, evidence-backed starting point, and for many women, it may be the only step you ever need. Start with the Solasta laser.
If your main struggles are painful sex, low sexual satisfaction, or a deeper ache or pressure in the pelvis, The evidence right now more strongly supports an internal, direct-contact approach for those specific issues. Vaginal and vulvar mucosa is thin and extremely responsive to light when the device makes direct contact rather than working through skin from the outside which likely explains why internal or combined approaches have shown benefit in areas the external-only study didn't.
If you're undecided, new to all of this, or specifically avoiding insertion because of vulvodynia, vaginismus, past trauma, or simply not feeling ready - start external. There is no evidence that beginning this way causes any delay or harm, and every reason to believe it's a sensible, lower-barrier entry point. Think of it as learning to swim in the shallow end first. You get real, measurable benefit for a meaningful set of symptoms, you get comfortable with the idea of light therapy as part of your care, and if you eventually want to explore an internal approach for symptoms the external method doesn't address, you can graduate to that when and only when you're ready. Nobody should have to push through fear or pain just to access care, and starting externally means you never have to.
If avoiding insertion has meant avoiding treatment altogether, that's the real problem I want to solve for you today. A real, published, placebo-controlled study shows that external light therapy, no insertion, no probe, just light applied to the outside of the tissues can meaningfully help with urinary leakage and vaginal dryness and burning. It's not a cure-all, and I won't pretend it is. But it's a legitimate first step, and for a lot of women, it may be exactly the right amount of treatment for exactly the symptoms they're dealing with.
If you want to talk through which approach makes the most sense for what you're personally experiencing, that's exactly the kind of conversation I have with clients every week - because the right answer depends on you, not on which product happens to be trending. Contact me with questions.

Frequently Asked Questions About External Light Therapy for Menopause
Does red light therapy really work for vaginal dryness if you don't insert it?
Yes. Clinical research shows that applying external 808nm near-infrared light to the vulvar tissue can significantly reduce vaginal dryness, burning, and urinary leakage. Because the superficial tissue and supportive urethral muscles sit just millimeters beneath the skin, the light reaches the target area without requiring internal insertion.
Is external light therapy as effective as an internal pelvic wand?
It depends on the symptom you are treating. External light therapy shows strong, evidence-backed results for urinary incontinence, superficial dryness, and rawness. However, for issues like pain during intercourse (not associated with lubrication level) or deeper pelvic pressure, internal devices that make direct contact with vaginal mucosa are currently more strongly supported by clinical studies.
How deep does near-infrared light actually penetrate soft tissue?
Near-infrared light (typically around 808nm wavelength) penetrates soft tissue to a depth of roughly 5 to 10 millimeters. This shallow penetration depth is ideal because the urethra, sphincter muscles, and vulvar vascular networks lie directly within this top layer of tissue.
Can light therapy cause tissue burns or side effects in delicate areas?
Photobiomodulation (PBM) uses non-thermal LED or low-level laser light, meaning it does not burn, cut, or heat delicate genital tissue like surgical or ablative lasers do. When used as directed, external PBM is non-invasive, painless, and carries minimal risk of side effects.
How long does it take to see results from external PBM for GSM?
Light therapy works on a cellular level by boosting mitochondrial ATP production and local blood circulation, which takes time to rebuild tissue tone. Most clinical protocols involve bi-weekly treatments over 4 to 8 weeks before women notice significant improvements in dryness and bladder control.
Is external light therapy safe if I can't take hormone replacement therapy (HRT)?
Yes. Photobiomodulation is entirely non-hormonal. It stimulates cellular energy production and releases nitric oxide to improve local microcirculation, making it a viable alternative for women who cannot or choose not to use estrogen therapy, including breast cancer survivors.
